LabSen 841 Refillable pH Electrode for Strong Alkaline Solutions and High Salinity Solutions, BNC/RCA Connector

• Robust Swiss HA-type glass membrane designed for strong alkaline solutions (pH 12-14) and high salinity solutions (>5000ppm or 0.5%), minimizing alkaline errors.
  
• Silver Ion Trap Reference System - On top of the Long-Life reference system, a silver ion trap is added to further prevent junction clog.
• LabSen's sturdy glass membrane, 10 times stronger than traditional glass membranes
• The blue gel electrolyte eliminating the chance of any air bubbles inside the sensor

Backed by proprietary sensor technology and premium materials from Switzerland, Apera LabSen 841 Glass pH Electrode is designed for high-precision pH measurement of strong alkaline solutions (12 to 14 pH) and high salinity (>5000ppm or 0.5%) solutions.

Robust LabSen HA Glass Membrane – the special type of membrane minimizes alkaline error down to 3 mV in strong alkaline or high salinity solutions.

Built tough – The hemispherical glass membrane is 10 times stronger than traditional glass membranes, highly resistant to general impact, saving the electrode from accidental damage.

Silver Ion Trap Reference System – On top of the Long-Life reference system, a silver ion trap is added to further prevent junction clog.

The electrode uses a standard BNC connector, compatible with any pH meters that use BNC connectors. No temperature sensor is built-in. Users need to have a separate temperature probe (ex: Apera Instruments MP500) to enable ATC or manually input temperature to realize temperature compensation.
